中文摘要：
针对大量非色唯一图，利用图的伴随多项式，最小根及其特征标的性质研究了一类稠密图的色性：完整刻画了该类稠密图的色等价图类，并给出了其色唯一的充要条件．这为图的色性研究提供了新的工具和方法．
英文摘要：
In allusion to a large number of non-chromatically unique graphs, the chromaticity of a class of the dense graphs is studied by applying the properties of graphls adjoint polynomial, minimum roots and character features. The chromatically characterized, and the chromatically unique s The new tools and methods are provided for equivalent classes of the dense graphs are completely ufficient and necessary condition of the graphs is obtained. the chromaticity research of graphs.
